Suppose a computer program has been initialized such that the following sets have been stored for use in any algorithm:

A $=\{1,2,3,...,43\}$

B $=\{-7,-6,-5,...,30\}$

Consider the following algorithm, which represents one part of the whole computer program $($comments may occur after the # symbol on any line and are not used in computations$)$:

#Part $1$: computes A $-$ B and its cardinality

AminusB $=$ set$()$

for element in A: # this line runs through every element in A

if not$($element in B$)$: #A $-$ B is the set of elements that are in A and are not in B

AminusB.add$($element$)$ # Add to AminusB every element in A if the element is also not in B

n $=$ len$($AminusB$)$ #len$()$ returns the number of elements in the array

print$($n$)$

What value is printed as a result of executing this algorithm?
